Pam Feerce was a human who in 2009 had been manipulated into caring for a mind-controlling alien baby. Pam cut off all ties with family and friends, sacrificing her life and physical health to care for the child. The baby made her steal food and supplies it wanted, and even made her kill Alex Brown, Bobby Pembroke and Rhett Seyers in perceived self-defence.
Because of her complete devotion to the baby, Pam was nicknamed "pram-face" by a gang of teenagers from the Machen estate. When Gwen Cooper intervened after seeing Pam being harrassed by the teenagers, Pam left as quickly as she could and dodged all of Gwen's questions. Pam was also elusive to Kenrick Jones, who had been appointed as her social worker and was afraid of her and the unregistered baby getting lost in the system.
When the alien baby released its grip on Pam, using Gwen as its new host, Pam confessed to Jack Harkness that she had been feeling suicidal. While she had her free will back, Pam killed the baby and herself with the self-destruct feature of a Torrosett 51 binary heat-cannon. (PROSE: The Wrong Hands)
